STX790A Medium current, high performance, low voltage PNP transistor Features Very low collector to emitter saturation voltage DC current gain, hFE > 100 3 A continuous collector current 40 V breakdown voltage V(BR)CER Applications Power management in portable equipment TO-92 TO-92AP Voltage regulation in bias supply circuits Switching regulator in battery charger applications Heavy load driver Figure 1. Internal schematic diagram Description The devices are manufactured in low voltage PNP planar technology by using a "Base Island" layout. The resulting transistor shows exceptional high gain performance coupled with very low saturation voltage. The STX790AG-AP is supplied using halogen-free molding compound. Table 1.
